How many different types of genetically different gametes will be produced by a heterozygous plant having the genotype AABbCc?
Correct answer: D. Four
- A. Six
- B. Nine
- C. Two
- D. Four
Explanation
For the provided genotype AABbCc, which indicates homozygosity at all three gene loci, there are only four genetically different gametes produced. The gametes are ABC, AbC, ABc, and Abc. This is because there is no segregation of alleles for each gene, as all gene loci are homozygous.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
